Is the metal TO-3 case too expensive to manufacture? I don’t think the mixing console it feeds will draw 1. The PS is rated 1. Your name or email address: Register Log in Shopping cart 0 You have no items in your shopping cart.
Remember that heatsink paste only complements the contact – fill the air voids. Of course if you have to deal with insulation, you’re screwed. That’s what I did it worked fine. Funny, I have a new old stock that I purchased in for a power supply project and ended up using a to instead. I think I’m going the TO route I can get it locally.
Maximize air space around it as well. Other possibilities include adding a series pass transistor or diode drops so that the Ddatasheet doesn’t take the brunt of the drop.
Why this Voltage regulator is so expensive ??
Specifications Contact Us Ordering Guides. Is the TO-3 version much better than the plastic TO? I’ll check the mixer specs to see if I need a second device in parallel, but I think with 25W it will be fine. Mouser link Ratasheet Affiliation https: Pict from the internet, not mine: Adding a much bigger heat sink mounted to the chassis top plate really helped.
Is it due to availability? The new type of capacitor has a space-saving design with two, three or even ten identical capacitors connected in parallel on the same terminal to increase the capacitance. You could mount the regulator somewhere else to make it easier to add one if needed as sKiZo suggested.
If it blows this next month I’ll modify the circuit to install To devicesperhaps with a resistor in parallel. Lavane and Pio like ml7812k. Why this Voltage regulator is so expensive??

NTE is the replacement and cost less. I’d also be getting the TO and heat sink it as necessary. Please review product page below for detailed information, including LMK price, datasheets, in-stock availability, technical difficulties.
You can always stretch the leads to fit the board. You may still need to check whether the circuit will support the extra current from the ADJ pin. The former will require significant redesign however. Is it some very special part? It’s been a year so far and not one time has it shut down from over heating. Torque down properly – don’t overtorque and cause the flange to bend or too little, leaving air voids. One was an NTE and I wanted to replace it but saw the prices you did and thought otherwise.

It’s datasehet that not many are made in T cases. You may be better off drilling new holes for the TOs, using the existing TO-3 holes may not work well. I’m running a dual regulator right at its max rating to regulate a pair of B tube filaments. Yes, my password is: Check the 78xx regulator application notes for how to use a high power parallel bypass transistor to make a high current regulator.
You want metal-metal contact ideally, not through heatsink paste. Careful, bare metal contact is always better than adding anything in between – especially air voids.
LM7812CT, LM7812CV, LM7812K
Main problem of doing so is that the thermal resistance of the TO-3 is better than TO Is my math right? You’re probably best off retrofitting with a TO however. LavaneJun 24, Share This Page Tweet.
